DEVICE FOR TRI PPING VIBRATING TONGUES 0F MECHANICAL MUSIC-BOXES.

SPECIFICATION forming part of Letters Patent No. 629,259, dated July 18,1899.

Application filed December 2,1897- Serial No. 660,510. (No model.)

To all whom it may concern.-

Be it known that I, ANDRE JUNOD, a citizen of the Republic ofSwitzerland, residing at Auberson, Canton \Vadd, Switzerland, haveinvented certain new and useful Improvements in Devices for Tripping theVibrating Tongues of Mechanical Music-Boxes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as willenable others skilled in the art to which it appertaius tomake and use'the same.

According to this device the center of the tripping-wheel revolvesaround a fixed point located outside of said center, so that thereby thetripping-wheel is vertically displaced against the music-sheet.

In the accompanying drawings the tripping device is shown in twomodifications.

Figures 1 and 2 represent one form in side elevation, showing thetripping-wheel in different positions. Fig. 3 is a similar view of amodified form of the invention, and Fig. 4 is a transverse section ofthe same. Fig. Sis a detail of the support I), showing one of thecircular openings for the disks 0.

In Figs. 1 and 2 the tripping-wheel a is revolubly and concentricallymounted upon a disk 0, which is eecentrically pivoted upon a pin Q1 inthe frame Z) and is limited inits oscillations upon pin 2' by aprojection c. The tripping-wheel can turn freely upon said disk 0, whichis under the influence of a spring h, so that the tripping-wheel a ispressed constantly against the perforated music-sheet cl. "When a holein the music-sheet passes over the tripping-wheel, a tooth of thelatter,pressing against the music-sheet, will jump into this hole byvirtue of the spring, and the disk 0 will follow in turning upon itseccentric pin or pivot until it reaches its upper limit, when theprojection c strikes against the frame. Thus the tripping-wheel has forthe moment a hearing which is stationary, and the tripping of thevibrating tongue will be effected.

In the modified form shown in Figs. 3 and 4 the tripping-wheel a isrevolubly mounted between two disks 0 and eecentrically to the same,which latter are adapted to turn in correspondingly circular recesses inthe frame I). The disk 0 and tripping-wheel are connected by pin t. Therange or play of these disks 0 is limited by projections e, which movein the openingf of the frame I), and said disks areunder the action ofsprings It, so that the tripping-wheel is always held pressed againstthe in usic-sheet d. W hen the tripping-wheel is moved against one ofthe tongues g, the disks 0 are held in the position shown by theresistance of said tongue, and thus the trippin g-wheel is actuallyinstationary bearings. Under the tripping the wheel a is pressed downwhile the music-sheet advances and the disks 0 are turned in theirrecesses, thereby producing an advance or oscillation of the trippingwheel around the pivots of the disks 0.

I claim A tripping device for steel tongues in mechanical music-boxesconsisting of a tripping- Wheel a revolubly and concentrically mountedupon a disk 0, which is eecentrically pivoted in the frame, and whichreceives the pressure of a spring in such a way as to keep the teeth ofthe tripping-wheel constantly pressed againstthe music-sheet d, saiddisk being provided with a projection 0, adapted to limit theoscillation of the disk by striking against the frame Z) when a tooth ofthe tripping-wheel enters into an opening of the music-sheet.

In testimony whereof I affix my signature in presence of two witnesses.

ANDRE JUNOD.
